' Specification of Letters Patent.

Patented Mar. 30, 1915.

Original application led October 20, 1905, Serial No. 283,615. Divided and this application tiled May 19, 1909. Serial 1101.496975.

To all 'whom it may concern:

vBe it known that I, SIMEON ScHooN son', a subject of Great Britain, residing at Readville, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Wett-Replenishing Looms, of which the followmg -is a specification, reference being had therein to the accompanying drawings.

This case is a division of my application for United States patent for weft replenishing looms filed October 20, 1905, Serial No. 283,615 upon which Letters Patent No. 915,722 were granted under date of Jan. 4, 1910.

In the drawings-Figure 1 is an elevation of the driving end of a loom, with certain parts broken away, showing chieiiy the driving and stopping arrangements. Fig. 2 is a plan of the parts which are represented in Fig. 1, omitting the lay. Fig. 3, Sheet 2, is a partial elevation of the replenishing end of the loom, certain portions beingin sec- 2, is a partial plan of the lay and the parts which are mounted thereon at the replenishing end. Fig. 5, Sheet 3, shows in front elevation the breastbeam and portions of the opposite sideframes, together with the pick-finderI devices and connected parts which are mounted thereon, the middle portion of thelength ot the breast-beam being broken out for convenience in showing `the parts on a sufficiently large scale for clearness on one sheet ot drawings. Fig. 6, Sheet 3, shows in plan the parts of Fig. 5.- Fig. 7, Sheet f1, is a J ACK- detail vier.` showing the parts which are located at the left-hand end of the breastbeam, looking from the left-handside in Fig. 5. Fig. 8, Sheet f1, is a view of the parts which are shownin Fig. 7, but looking `from the right-hand side in Fig. 5, the breast-beam being represented in vertical transveise section. Fig. 9, Sheet 2, shows in front elevation a portion of the actuating mechanism and controlling connections for the change-shaft. Fig. 10. Sheet 4, is a partly sectional detail view showing chiefly the substitute weft devices.

Having reference to the draWings,-At 1, Figs. 1, 2, and 5, isthel side-frame at the driving end of the loom which is shown in the drawings, 1a in Figs. 3, 5, and 6 being the side-frame at the replenishing end of such loom. At 2, Figs. 2, 5,V 6, etc., is the breast-beam. The crank-shaft of the loom is shown at 3, Figs. 1, 2 and 3, and the'camshaft at 4, the usual gears by means of which motion is transmitted from the crankshaft to the cam-shaft being shown at'5, 6, Figs. 1 and 2. Having reference to the driving connections, and to the shipper and brake-devices of Figs. 1 and 2, a loose-'bandpulley 7 is mounted upon the crank-shaft 3,

driving-power being transmitted to the said band-pulley by means of a suitably-actuated driving-band 8, Fig. 1,.pas'sing around the same, while 9 is a wheel fixed upon the crank-shaft, the two wheels 7 and 9 being provided with or constructed to constitute the inter-engaging members of a frictionclutch.v At 10 is a clutch-operating lever which is pivoted at 101 upon the stand 1", Figs. 1 and 2attached to the loom-side 1 and extending outward therefrom, the said lever having a fork which engages with a yoke 102 in connection with the hub 71 o1 the loose band-pulley 7. 11 is a rod connecting thev clutch-operating lever 10 with the upwardly-extending arm of the bell-crank 12, which latter is mounted upon a stud 121 carried by and projecting outward from the loom-side l., the said bell-crank having a forwardly-extending ar'm 122 by means. of which the same may be operated for the purpose of actuating the lever 10 to move the band-palle)7 7 toward and from the wheel 9 as required in order to close and openthe friction-clutch.

13 is a brake-wheel which is fixed upon the crank-shaft 3', and 14 is a brake-band which extends partly around the periphery of the said brake-wheel, one end of the said brake-band being connected to yan adjustable eye-belt 15 that is carriedv'byv a stand 151 projecting from the loom-(arch, while the other end of the said brake-band is connected with the uiiwardly-extending arm of a i means whereof the bell-crank 16 may be manually operated when desired. To the said arm 161 is connected one end of the strong A contracting spiral spring 17, the other end of which is connected to an eyebolt 171 that is carried by a stand 18 projecting from the loom-side 1. Normally the arm 161 of bell-crank 1G is held upraised with the hell-crank occupying a position in which the brake-band is slack around the brake-wheel 13. 'When the bell-crank 16 is freed to the control of the said spring 17, the latter operates the bell-crank to tighten the brake-band 14 upon the periphery of the brake-wheel. In order that the move; ment of the bell-crank 1G under the action of the. spring may also transmit movement. to the clutch-operating lever 10, to open the clutch and-thereby disconnect the driving power, the armgll is furnished with a pin 162, which projects transversely from the said arm across' the top of the arm 122 of bell-crank 12. lVhen bell-crank 16 is operated by its spring 17, the descent of arm A161 causes the arm 122 of bell-crank 12 to be pressed down by the said pin 162, thereby transmitting to the clutch-operating lever 10 movement in the direction to separate the clutch-members and thus discontinue the application of driving-lmwer.

For .the purpose of enabling the bellcranks 12, 1G, to be operated simultaneously in starting the loom, so as to throw off the brake and efect the clutching of the bandpulley 7 to the crankshaft, the arm 122 of the hell-crank 12 is furnished with a latemily-"projecting pin 123, Fig. 1, which extends through a slot 191 formed in the lower end of a rod 19, the said slot extending in the direction of the length of the rod, the upper end of which latter is pivoted at 192 to the shipper-handle 20, which last is fixed upon one end of the horizontal stopping rockshaft 21, the said rockshaft extending across the loom beneath the breast-beam, and being mounted in suitable bearings with which the side-fraii'ies 1, 1, are provided. Movement of the shipper-handle forward causes the rod to move endwise, and h v engagement of the wall at the lower end of slot 191 with the pin 123 the bell-crank 412 is turned to clutch the band-pulley 7 to the crank-shaft, the engagement of the arm 122 of the said bell-crank with pin 162 on arm 161 of bell-crank 16 causing the latter bellcranlt to be turned so as to slacken the brake-band. ln the position normaliy oecupied by' the shipper-handle during the running of the loom', the point of connection '192, between the rod 19 and the shipper-handle 4is slightly forward of the center of the stopping rockshaft 21, whereby the parts are locked in working position. lVhen the shipper-handle is moved reversely so as td carry the said point of connection to the rear side of the center of rockshaft 21, the spring 17 acts to move the bell-cranks toI apply the brake and disconnect the drivingpower.

Other constructions and arrangements of driving, shipping, and braking devices may be employed in practice.

Figs. 3 and 4 show certain parts of weftreplenishinginstrumentalities. In the said figures 22 is a hopper for fresh or reserve shuttles, the said hopper being supported in place at the replenishing end of the loom, adjacent one end of the( breast-beam.

23- is a shuttle-support, which is pivotally mounted at 231 in connection with the hopper, and furnished with rearwardly-projecting lingers that normally occupy a. position beneath the bottom shuttle inthe honper, supporting such shuttle and the others which rest upon the latter.

24 is the injector, its supporting lever being mounted pivotally at 241 upon the lower part of the loom-frame. The short arm of the said lever is provided with a roll 242, which latter is held pressed in contact with the periphery of an edge-cam 243 that is carried by the change-shaft 25, by the tension of a contracting spiral spring 244 having one end thereot engaged with the injector-lever and the other end thereof engaged with the eye ot' a bolt 245, applied to a bracket 246 which is attached to the loomframe. Normally the change-shaft, together with the cams which are fast thereon, stands motionless in the position represented in Fig. 3, and the injector occupies the position beneath the hopper which it occupies in such figure. When the change-shaft is caused to rotate, a preliminary movement of the injector toward the. t'ront of the loom occasioned by cam 243 carries the injector against a downwaidly-extending linger 232 of the shuttle-support, moving the latter forward so as to withdraw its rearwardlyextending fingers from beneath the bottom shuttle in the hopper and permit the contents of the hopper to drop until the bottom shuttle rests upon the horizontal 4shuttlesupporting portions of the injector. The spring 244 next operates to move the inl jector with yielding force rearward toward the lay, under the control of the cam 243, vto place the shuttle which is heldthereby within the shuttle-box at the replenishing end of theloom, after which the said cam acts to communicate positive movement to' Y front-plate 26 is held depressed in its workfrom the shuttle-box and a fresh or reserve' shuttle to be inserted into the latter through the'action of the injector. The front-plate 26 is carried by forwardly-projecting arms 261, 261, forming part of a rocker 262, the rockshaft of which last is pivotally mounted in bearings that are provided in brackets 263, 263, which are. attached to the lay-beam and rise at the rear thereof. Normally the ing position, so as to keep the shuttle-box closed, by means of a contracting spiral spring 264, Fig. 3, having one end thereof connected to one of the forwardly-project ing arms 261 of the rocker and 'the other end thereof connected to one of the brackets 263.

For the purpose of operating the rocker to raise the frontplate to open the shuttlebox to permit of the discharge of the spent working shuttle and the introduction of a fresh or reserve shuttle. the rocker is pro vided with a rearwardly-projecting arm 265 having connected therewith one end of a connecting-rod 2.66, the opposite end of which is connected to an arm 267. which is pivotally mounted at 268 and provided with a projection that is engaged by the periphery of an edge-cam 269 which is fast upon the change-shaft. lx1-the rotation of the change-shaft, the cam 269 transmits Inovement through the arm 267 and connectingrod 266 to the rocker to raise the front-plate from its normal closed position and thereby open the shuttleliox. The spring 264 acts to move the rocker in the reverse direction under the control of the cam 269. to lower the front-plate to its normal position and thereby close the shuttle-box again, An ejector 27 is mounted by means of brackets 271. Q71, upon the back of the shuttle-box. the said ejector being formed as a rocker having journals which are fitted to bearings in the said brackets. and having lingers which project into openings at the rear rf the shuttlelfox as indicated in Figs. 2% and The ejector is held retracted normally by the tension of the contracting .spiral spring 272. the latter having one extreinitv thereof engaged with a screw or tht` like projection carried by the rockshaft of the ejector. while the'other end of the said springY is connected with a strap that wraps part way around the rockshaft of the ejector and is attached b v its inner end to the said roclnfhaft. A finger 273 projecting from the ejector takes against the under side of the rockshaf'r of the rocker 262, and serves to limit the extent of the retraction of"` the ejector under the action of the, spring '272. A linger 274- projecting forwardly from the ejector is pressed against by one of the arms ,461 of the rocker 262 in the movement of the rocker by which the front'plate of the shuttie-box is raised, and thereby the ejector is actuated to eject the spent working shuttle from the opened shuttle-box. The ejected shutth` falls from the said shuttle-box on to a llexible apron 28. theI latter being connected at its upper end with the front of the lay-beam and passing forward from the lay-beam over a transmise rod 281 which is supported at the rear of the shuttle-receiving box 282, the latter being attached to the adjacent side-frame of the loom. The shuttle slides from the apron into the said box. The apron plays back and forth over the rod i281 as the lay vibrates, and thereby accommodates itself to the varying positions of the lay, it serving to conduct the ejected shuttle into the box 282 whatever may be the position of the lay at the time of the ejection.

The change-shaft normally stands at rest. For the performance of the replenishing operation the change-shaft with its various cams is called into action. A dwell in the working of the weaving instrumen'talities is brought about by causing the braking devices to unclntch the band-pulley 7 from the wheel 9, and by also causing' the braking devices to apply the brake. On the conclusion of the replenishing operation the said weaving instrumentalities are restarted by again clutching the band-pulleyv to the wheel 9 and taking off the, friction of the brake. after which the change-shaft comes to rest.

The means of communicatinf.r rotary motion at the proper time to the change-shaft, and subsequently discontinuing such inotion. is shown in Figs. l, 2, and 9, 0f the accompanying drawings. In Figs. l and 2 the loose band-pulley 7 has fast therewith a bevel-gear 7l() meshing with a bevel-pinion 72 which is fast upon the upper end of an inclined shaft 73. the said shaft at its lower end being furnished with a worm 74 mesh ing with a worm-gear 75 that is mounted upon the change-shaft Q5 with capacity to turn freely,thereon. 'l`hroug'h the driving# connections between the loose pulley 7 and the worm-gear 75. the latter is constantly rotated. During the ordinarj.' running of the loom. this rotation of the wornrgear is unaccompanied by motion of the changeshaft. dien the change-shaft and its cams are required to act. the worm gear is clutched to the change-shaft. 'Io enable the clutching to be effected. a disk i251. Figs. Q and 9, is fixed upon the ehangewshaft. with the outer face thereof close to the inner face of the 'wornrgeaiz To the inner face of the said fixed disk 251 a clutchingdever 252 is pivoted at Fig. The said levereXte/nds diametrically with relation to the disk 251, and swings toward and from the disk. One arm of the said lever is -furnished with a projection 254 working in a hole 255 that is made through the disk.

In the Worm-gear 75 is Aformed a circular series of holes 751, 751, etc., Fig. l, eaqh adapted to receive the projection 254 when in position in line with the latter. The lever 252 is acted upon ov a spring i256, the latter tending to turn the lever into a position in which the projection 254 shall project through the disk 251 and enter into one of the. holes l, 75l, of the wornrgear 75. So long as the lever occupies a position with its projection withdrawn from the woriirecar 75 into the hole 255, the woringear is free to turn upon the change-shaft, M independently of the latter, and the change shaft remains motionless. The lever is held normally in its withdrawn or disengaged position, against the tendency of the spring 5o to turn the saine so as to carry-the projectioii Q54 toward the worin-gear 75, by means ol an iiiicliitching arin 257, Figs. 2 and 9. which is pivoted at its lowei` end upon a fixed stand 258, its upper end being ohliquelv disposed with relation to the plane of rotation of the disk 251, and Somewhat rounded. To the said :irin is pivotally connected a hitch 259, that is adapted to engage with a shoulder 260 on a l 1acket connected with stand 2.38. the said latch heine,- held norinallv in engagement with the said shoulder hv ineansv ot a coiitractingspiral spring ifftdl 'iavinjgj fir-e end thcreoi' joined to thc hitch and the other end thereof joined to the outer portion of stand 25S.

Having` reference. now` to the piclclinder devices which are shown in the drawines; theseI consi t. essentially. in wett-detector :neans detectingr toi' the successive picks to the respective sides of the looni, andrcon tioliing'the operation of the loom-mecha nisni wiih timingr to cause the lirst pick of fresh weft to be introduced into a reopening of the shed in which failure tookplace, after one or a plurality of rounds or cycles of shed-formations. The said pick-finder devices are combined herein with t-he stopping mechanism and the replenishing mechanism.

ln thedra\vings,-30 is a weft-fork which is located 'at the replenishing end or side of the loom, at 31 is the weft-fork slide or carrier on which the said weft-fork is pivotally mounted, at 32 is the guide for said slide or carrier, the Said guide being secured by a screvv 33 to the breast-beam 2, at 34 is the weft-hammer or gooseneck coiiperating with the said weft-fork 30, and at 35, Fig. 8, is the cam, upon cam-shaft 4, by means of which the weft-hammer or gooseneck 34 is actuated. The cam 35 is shaped and timed to cause the weft-hammer or gooseneck 34, While the lay is forward after the pick to the replenishing side, to advance far enough to engage the tail of the weft-fork 30 in case the weft should have failed in such pick, then dwell until after the pick of the spent or failed' shuttle to the driving side of the loom, and complete its advance after the return pick of such shuttle to the replenishing side. It will be perceived that, counting the pick toward the replenishing side of the loom in which failure of weft took place as the first, the return pick to the replenishing side is the third. pick of the sequence. It also will be perceived that if the harness-movements comprise three shed-formations to the round or cycle, the shed for the pick which should neXt succeed from the `replenishing side, namely the fourth shed,

will he the same as the shed for the pick in which the said failure took place. If, therefore. after the return of the spent or failed shuttle to the replenishing side of the loom on the third pick the Working weft-supply be repleniished, either by manual intervention or automatically, prior to the occurreneix of the fourth pick, the tirst pick of` fresh weft will be introduced into a reopening of the proper shed to receive it, such reopening occurring after a round m' cycle of shed-formations.

The weft-fork devices at the replenishing side of the loom shown in the drawings are oiwraively connected and arranged to ope'l ate normally to cause replenishment to occur automatically following the said third pick. For such purpose, the weft-fork slide ory carrier 31 has applied thereto a stud 341 projecting forward and provided in its forward end with a transverse hole or slot receiving a sind or pin 351 which projects latcrallv from an arm 36 rising from a rod l? elija hich such arm is fixed. The said rod iii' is suppm'red in position adjacent the lower front edge of the breast-beam. and eatends crossuis-r ol the loom. At one end thereof it is fitted to a bearing 371, Fig. 5, which is attached to the breast-beam. The other end of the same enters the central eye of the hub of arm 41 hereinafter described, I

ser Fig. 5. and fits loosely therein, whereby such end is supported. Upon the end of said rod adjacent the driving side 0f the loom a second upwardly-extending arm 38, Figs. 5 and 6, is fixed. The said arm 38 has pivot-ally mounted upon a stud 392 projecting laterally from its upper end a dog 39, Figs. 5, 6, and 7, Which is provided with a lateral engaging projection 391. projection extends over the upper end of the arm 41, the latter rising from a short rod 411 which is supported in line with rod 37 by a fixed bearing 412, and upon the inner The saidv end of which rod the arm 41 is fixed. The

instrumentalities, the rod 411 is furnished with an arm 43, Fig. 2 projecting rearwardly therefrom and joined by a flexible or other connection 44 with the latch 259, Figs. 2 and 9, so that when the parts are rocked asjust mentioned the said latch is disengaged from the fixed shoulder 260 and the unclutching arm 257 is unl-etched or unlocked, allowing the spring 256 to turn the clutching lever 252 and clutch the Wormgear 75 to the change-shaft. For the purpose of transmitting movement to the shipper-handle 20 to bring about the stoppage of the weaving instrumentalities With the shuttle in the shuttle-box at the replenshing end of the loom, the rod 411 has fixed thereon a h/ub 45, Figs. 5 and 7, having a. projection 46, Figs. 1 and 7, for engagement with a projection 47 from the shipperhandle. When rod 411 is turned as aforesaid, the action of projection 46 against projection 47 operates to turn the` shipperhandle to carry lthe line of draft'that is transmitted by means of the rod 19 from brake-lever 12 to the shipper-handle 20 to the rear of the center of shipper-rogkshaft 21, unlocking the shipper-devices, ,Whereupon the spring 17 acts to effectuate the unclutching of the band-pulley 7 and the applicatitn of the brake. For the purpose of varying the timing in theevent of failure of the weft in the pick from the replenlshmg side of the loom to the driving side thereof, a supplemental weft-fork 50 is located at the driving side of the loom. 51 being the weft-forked slide or carrier on which the said weft-imi( is pivoted. 52 is the guide in which the said slide or carrier 51 is fitted,

the said guide being secured upon the breasbheam by screws 53, 53, Figs. 5 and 6.

54 is a iveft-haniiner or gooseneck coperating with the supplemental weft-fork 50, and 55, Fig. 1, is a cam upon cam-shaft 4 by means of which the weft-hammer or gooseiieck 3l is actuated. The weft-fork slide or carrier 5l has applied thereto a stud 5G, projeeting from the front end thereof toward the tient of the loom, and having in its free end a transverse hole or slot receiving a pin or the like, as at 5i', projecting laterally from -in ai-ni, 3S, which is sleeved upon the rod `with capacityA to turn freely thereon. iovement imparted to the weft-fork slide or carrier 51 is communicated to t-he arm 58 by means of the stud 56 and its engagement ivith the projection 5T oi. the said arm. Upon the upper end of the arm 58 is fastened a disengaginoj piece 5S), the latter having an inclined cam-portion for action against a pin or other projection, 393, extending transversely Jfrom the dog: 39 across the.

front ot' the said discngaging piece. The said inclined cam-portion of the disengagingr piece is designed to act against the said.

pin or projection 393 under certain condi tions, when the weft-fork slide or carrier 5l and arm 5S are inored toward the front of the loom in consequence of the engagement ot the iveft-haiiimer or gooseneck 5ft with the tail of iveft-t`oik 5U, and when the camportion acts against the said pin or projection it operates to lift the dogr 39 so as to raise its engaging projection P191 above the shoulder 42 of the arm il. Thereby the rocking* of the rod 3T a nd its arm 3S toward the fiont ot the looiu, resulting: from the aetion ol weft-hammer oi' Looseneclt 34 iii connection with the wett-fork 30, is rendered ineffective to operate the controlling and transmittine;l device. contractingr spiral spring vl1` haing' one end thereoi5 attached to the lived guide 512 and the other end thereof attached to a lug projecting` laterally from arm 58, acts to move the said arm and the iveft-fork slide or carrier 51 rearivard in the loom, after they have heen adi anced toivard the l'i'oiit by the, action of the veit-hammer or frooseiieclc 51, as soon as the spring'r is permitted so to do b v the rearward return stroke. ot' the said weft-hainn'ier or gooseneck.

The cani 55 by which the wett-hammer or grooseneek 5l is operated is shaped and timed to advance tl'ie latter, followingr a pick from the replenishing side ot' the looin to the drivintlr Side, tar enough to engage with the tail of the wett-fork 50 in ease otl failure of weft in such piek, then cause the said weft-hamnier or gooseneck to move very slowly `to ward the front until after the pick from the driving side to the replenishingr side, and then cause the saine to dwell iii its :idvaneed position until a tter the irst portion of the advance of the wefthaninier or goosencck 34 at the replenishing side of the loom has taken place. Upon the pin pr stud 391%, projecting laterally from the arm 38 of rod 3T and upon which the du@ 39 is hung, also pivotally hung an arm 60 having its free rear end formed with a socket G1 within which is fitted a wire n2 extending rearv wardly alongside the weftfforlr slide or carrier 51 through a guide 53 with which the tired` guide is provided. The rear por tion of the said wire is heut upward at 64, as shown best in Fig. T, to form an incline for action upon a lateral projection (35 from the tail of the weft-fork 5t) The result, in tli-c Working of the loom, of the action oi' the supplemental weft-fork 50 and the asso-- ciated parts, on detection of failure of weft in a pick to the drivingr side of the loom, is to retard the effective operation of the detector-mechanism and postpone the stopping of the weaving instruinentalities, and also the replenishment, until following a return pick to the replenishing side subsequent to that on which the weft-detector mechanism at the replenishing side normally occasions the said action. v

In a loom -in which the return pick to the replenishing side of the loom preceding stoppage or stoppage and replenishment, corresponds with the final shed of an even multiple of around or cycle of shed-formations comprisingr three,I iii the present instance, or other uneven number of sliedtormat-ions, the first succeedi1152:y pick of fresh weft will be introduced into a reopening of the irst shed, namely, that in which failure of weft has occurred, which is the proper shed to receive such piek in order to avoid a defect in the weaving.

lt has been explained that the weft-fork l0 and parts more immediately associated iii action therewith, artingf on failure of weft in a piek to the ieiilenisliing side of the loom, are arranged to control the op eration ot' the stopping mechanism and repleiiishing mechanism so as' to causeI the saine to art with timid;r r e arrest the working ot' the wea ving insti-i; feiitilities :ind ef@ 't'eet the replenishment Aitt/wi' the round or c vcle of three shedforinations, and thereby secure theI introduction of the first pick of fresh weft into the proper `shed to receive it after such round oil cycle, namely the fourth shed, which is a reopening of the shed in which failure peeurred. The supplemental weft-fork 5l) and associated parts, on the other hand. are arranged to act on failure of weft in the piel( toward the driving side of the loom so to control the timing that the action of the stopping mechanism and reiilenishiiig mechanism is deferred unv til following the sixth pick, which corresponds with the final shed of an even multiple (2) of the round or cycle of shed-formations. whereby the first pick of freshv ward the front of the loom and be held forward until after the occurrence of the first portion of the advancing movement of the weft-hammer or gooseneck 34 at the replenishing side of the loom. In such advance of arm 58 and the disengaging cam 59 the said cam will raise the dog 39 so as tov lift its engaging projection 391 above the shoulder 42 of the arm 41, prior to the said portion of the movement of weft-hammer or gooseneck 34. Following the pick of the spent ory failed shuttle from the driving side of the loomto the replenishing side thereof. (which is the second pick of the sequence beginning with the pick to the driving side in which the failure of weft took place) the weft-Kammer or gooseneck 34 at the latter side, in being given its preliminary movement towardthe front of the loom, will engage with the weft-fork 30 in consequence of the absence vof weft to tilt the said fork. and will communicate a artial advancing movement to the weft-for( slide or carrier 31, partially rocking the rod 37 far enough to cause the engaging projection v391 of dog 39 to pass forwardly beyond the shoulder l2 of the arm 41, but as at this time the said dog is held in an uplifted position by the disengaging cam 59 the forward movement of the dog will take` place without engagement of the dog with the said shoulder. The dwell in the forward movement of wefthammer or gooseneck 34 Will retain the forward edge of the engaging projection 391 of dog 39 slightly at the front of the shoulder 42 of arm 41. The wire 62 is moved to the front a short distance as a result of the forward movement that is communicated to aim 3S, ov the rocking of rod 37. As the weft-hammer or gooseneck o4 moves rearward in the loom. the spring 511 draws the weft-fm-k slide or carrier 51 rearward also. In this movement of the said slide or carrier. the projection ($5 from the tail of the supplemental weft-fork 50 rides upon the said incline fil. tilting the weft-fork so as to raise its hooked tail out of the reach of wefthammer or gooseneck 54. By the rearward movement of the disengaging cam 59 oer'irrinej in unison with that of the slide or carrier Til. the dog 39 is lowered until its engaging projection comes to rest upon the top of arm 41 at the front of the shoulder 42. lVhen now the weft-hammer or goose neck 34 at the replenishing side of the loom completes its movement to the front, the en' gaging projection 391 of dog 39 simply plays forward idly. Following the succeeding pick from the replenishing side of the loom to the drivingr side (which is the third pick of the sequence) the weft-hammer or gooseneck 54 makes its beat toward the front of the loom. The weft-fork 50 having been tilted, however, by the incline 64 of the wire 62, such beat occurs without engagement of. the said weft-hammer or gooseneck with the said weft-fork. The beat therefore is an idle None. Consequently, the weft-fork slide orearrier 51 and disengaging cam 59 remain in their rearward positions, and dog 39 is permitted to occupy its normal lowered position in readiness to engage with the shoulder 42 of the arm 41.

The return movement of the weft-hammer or gooscneck 34 toward the rear allows the rod 37 to turn reverselv under the influence of spring 371, carrying the arm 38back so as to place the engaging rojection 391 at the rear of shoulder 42 o arm 41, and restoring the weft-fork slide or carrier 31 to its normal position. The backward movement of arm 38 also moves the wire 62 rearward so as to withdraw incline 64 from contact with projection 65 of weft-fork 50 and permit such weftvfork to assume its normal osition. On the return of the spent or failed shuttle to the replenishing side, namely on the fourth pick of the sequence) the weft'hammer orgooseneck 34 at such side again acts. engaging with the weft-fork 30. Its preliminary movement toward the front causes the dog 39 to be moved forward far enough to cause its engaging projection B91 to become engaged with shoulder 42 of arm 41, whereupon the dwell of such wefthammer or gooseneck takes place. This prelixuinarjv movement operates to turn the rod 3T so as to move the wire 62 forward again far enough to cause its incline 64 to tilt the `weft-fork 50 so that the succeeding moveinent or beat of weft-hammer or gooseneek 54 shall be an idle one. The shuttle now is picked to the driving side, (making the fifth o rkl. The weft-hammer or gooseneck 54 makes au idle beat as just described. lVhile the lay is still forward following this pick, the weft-hammer cfr gooseneck 34 at the replenishing side olif the loom completes its novemenl to the front. This time. in conse ouenee of the fact that the engaging projection 391 of dog 39 is in position to act against the shoulder 42 of the arm 11. the said arm and the rod 111 are turned to call the stopping mechanism and replenislnnzr mechanism into action. The shuttle if nieked from the driving side as thelav goes back (making the sixth piek) and inno lll diatel; afterward. as the lay arrives at or naar liacl: renter. the nearing instrumentnlities are brought to rest, the shuttle continuing its night until it is boxed at the replenislnng side. c

lt will be understood that, corresponding with the six picks beginning with that in which failure of weft occurred and ending with the stopping of the lWeaving instrumentalities. six sheds are formed in the uarp-thrczuls in succession, such number eonstituiing; a multiple of the round or cycle of shedformations llhen weaving operations are resumed after the replenishment has been eli'cctewh the shed that is opened for the introduction of the lirst pick ot' fresh vfet't is the seventh counting from thc shed in which the failure of weft occurred; that to say such shed is a reoi'rening of the latter shed, .it beninv a recurrence of the saine succeedingr a nre tiple or! the round or cycle or ,siied-lfozmat i. nseipiently, the said first pick oi' fresh Wett will be introduced into the proper shed to obviate a defect in the u'eavinff.

issuniing failure oi weft to occur in the picl'tovrard the replenishing side of the loom. and detection of the failure by the nett-detector devices at such side. with resulting preliminary action of such devices producing the partial advance oi' the dog 3f) which places its projection 391 in engagement with the shoulder -l ot arm 11, the

'Wetudetector devices at the diiving-side of the loom will act after the pick of the spent or `ailed shuttle to the latter side and in consequence ol the engagement of the tail ofy the weft-fork 5() by the weft-hammer 5l, and the resulting partial advance ot the uet'td'oilt slide or carrier 5l. the connected dif-engaging cam 59 will he moved toward the pin or stud 39?, ol the dog 39. However, lietoe the said disengaging 1 un reaches the said pin orslud and acts agr ist the same to e the dog and therebi7 shift the engaging poiee' in lill of the dog outloil engagement vrih tir shoulder 'ot' the arm 4l. the final portion ol' the movement of the weft-liana` nier 2li at the replenishing side of the loom n l take place. filth the result that ie coning' and iranfriniittingi member `will be operated to call the replcnisiiing mechanism and stopping' mechanism into action, as alrenday explained.

The which have just been described coostil uie dillerential delaying mech- :iui n rolled by weit absence which peren ci en number (tirol ot' idle picks and an ,4f-n number (two) of harness changes before the fresh ireiiii is supplied. in case the .vrltabf-:eiire detector at the replenishincr or magazinende oi' the loom first detects weitrbseiu'e .end nfli'nl permitsy an additional number olyidle pif-inf, and oit harness changes when the companion deter-tm' first detects wefbabsence, said additional number of harness changes being an odd number and equal to the number of harnesses.

In consequence ot' the 'fact that the stopn page of the weaving instrumentalities, for purposes of replenishment, that is occasioned by the action of the automatic deiices which have been described is caused to take place almost simultaneously with the pick from the driving side to the replenishing side, and before the weft-fork mecha nism at the replenishing side has performed its action corresponding with such ick, and

in consequence further, oi' the fact t at after the restarting of the said instrumentalities the said Weft-fork mechanism will act While the lay is forward in making its first beat, it is necessary to malcc provision for preventing the replenishinpr mechanism from being called immediately' into action again by reason oi the fact that the first pick from the replenishing side after replenishment leaves no weft in position to act upon the wefti'ork 30 at the replenishing side. In the loom shown in the drawings, this result is attained by means of the substitute-Wett devices which are shown in Fig. l0, Sheet 4. In the said figure, 67t is a lever which is pivoted at 68 upon or in connection with the lay-sword at the replei'iishing side of the loom, in this instance upon the pin or stud lioining the corresponding connecting rod or pitnian b with the said lay-sw0rd. The free end of one arm of the said lever is broadened somewhat to extend across or bridge one or more of the spaces of the grate (39 which is provided on the lay at one end oi the reed, lor cooperation with the nett-fork 30. The other arm of the said lever is joined by means of a connecting rod To with a lever 7G, the latter being pivoted at 77 upon a stand T8 which is attached to some convenient portion of the loom-fram ing'. The lever 76 is operatively controlled hjv means of a cam (3(5 upon the oliaiige-sliaft iv'hiie the change-shaft is at rest, the cam GG permits the parts to occupy a position in which the working end of the substitute-weft lever GT is withdrawn from proximity to the weftgrate (3S), thus permitting the tines ot' weft-fork 80 to pass through the openings of the we'ftgrate in the ab'- sence ol u'ei't in front of the latter. By the rotatien ot the change-shaft the cam 66 is caused to actuate the parts to more'lt succeeding.r the lirst pick after replenishinert.y so as to tilt the said weft-fork 1n the same nianncr as itwould be tilted by weft itsuch were present. rlhe final or concluding` portion of the rotation of the changeA shaft, occurring shortly fitter the Weaving Lim instrumentalities have heen restarted, presente. the drop of the cam (i6 to the lever iti, perinittingithe substitute-weft lever 6T to assume itslnermal position with its Working end withdrawn from the weft-grate (i9.

ln view of the fart that the worin-gear if is constantlyT driven from the bandpull i as longr as the driving-hand S passingr around said band-palle)Y is in motion, it is neeessarlv to malte provision against the aceidental starting up of the change-shaft during an ordinary stoppage of the loom hronght alight in' manual operation of the shipperdiandle 2o. For instance, it is neees- :tary to provide against the starting-up of the ehangewshat't in consequence of the actfon oll the welt-fork n'ieehanisinwhile the loom is lieing turned hv hand during stoppage. as trequentl)` is the ease in practice. to this end. lfurnish the dog 39 with a prolongation or extension ."05, Figs. 5, 7, and S. extending' downward therefrom, and I mount. upon the shipper rock-shaft 21 an arm or finger 31H5 which is set-screwed to the said roelishalt and provided atv its fiee, extremity with a transverse pro'ieetion PMT suitahle to malte eontaet with the said prolongation or extension 395 when the said roekshal't is turned for the purpose ot' oceasioning a lstoppage of the loomfmeehanism.
